Should I Have Been Eating Gluten Prior To These Tests?

My gastroenterologist ordered some blood tests for celiac; my results are below. His nurse told me based on the results that I don't have celiac and am not at risk for developing it. However, I had been on a gluten-free diet for months prior to the tests. (Occasionally some gluten slips in, but I am pretty careful.) Does that render the below tests invalid?

Your results are negative for antibodies related to celiac disease, but if you have not been eating gluten then there will not be antibodies--at least not enough to register on the test. I was retested a few years ago, and everything was normal. Does that mean that I no longer have celiac disease? NO! It means that I have been very successful in following the gluten-free diet, and there is not any gluten in my food to trigger the autoimmune response. :)

You need to be eating the equivelant of 2 to 3 slices of bread a day for about 2 months or longer for any chance of a positive test.

It looks like you have one or two HLA DQ 2 markers and that means that you are predisposed to developing Celiac Disease. I can't tell exactly what test they did - they call it a molecular test which may not mean they actually determined which DQ allele(s) you inherited so we can't tell whether you are high risk or low risk. Call the lab which did the test and ask them to tell you what it means and if you would get more information if you had the DNA marker test.

      Is this celiac?

      @Hmart, The reason why your intestinal damage was so severe, yet your tTg IgA was so minimal can be due to cutting back on gluten (and food in general) due to worsening symptoms. The tTg IgA antibodies are made in the intestines. While three grams of gluten per day for several weeks are enough to cause gastrointestinal symptoms, ten grams of gluten...

      Fiber Supplement

      Thanks, that's a great addition that I hadn't thought of.

      Other diseases, medical conditions, medications and even (for some people) some non-gluten foods can cause villous atrophy. There is also something called refractory celiac disease but it is pretty uncommon.

      ttg iga high (646 mg/dl) other results are normal

      knitty kitty asks a very relevant question. So many people make the mistake of experimenting with the gluten free diet or even a reduced gluten diet soon before getting formally tested.

      Fiber Supplement

      Another great fiber option is dried apricots. Four of them give you 3g of fiber and I find they don't produce all the gas that some other high fiber options do. They taste good too. Costco sells a large bag of them that are labeled gluten-free so you don't have to worry about cross contamination issues like you might in bulk grocery settings.

      @Hmart, The reason why your intestinal damage was so severe, yet your tTg IgA was so minimal can be due to cutting back on gluten (and food in general) due to worsening symptoms.  The tTg IgA antibodies are made in the intestines.  While three grams of gluten per day for several weeks are enough to cause gastrointestinal symptoms, ten grams of gluten per day for for several weeks are required to provoke sufficient antibody production so that the antibodies move out of the intestines and into the blood stream where they can be measured in blood tests.  Since you reduced your gluten consumption before testing, the antibody production went down and did not leave the intestines, hence lower than expected tTg IgA.   Still having abdominal pain and other symptoms this far out is indicative of nutritional deficiencies.  With such a severely damaged small intestine, you are not absorbing sufficient nutrients, especially Thiamine Vitamin B 1, so your body us burning stored fat and even breaking down muscle to fuel your body.   Yes, it is a very good idea to supplement with vitamins and minerals during healing.  The eight essential B vitamins are water soluble and easily lost with diarrhea.  The B vitamins all work together interconnectedly, and should be supplemented together.  Taking vitamin supplements provides your body with greater opportunity to absorb them.  Thiamine and the other B vitamins cannot be stored for long, so they must be replenished every day.  Thiamine tends to become depleted first which leads to Gastrointestinal Beriberi, a condition that doctors frequently fail to recognize.  Symptoms of Gastrointestinal Beriberi are abdominal pain and nausea, but neuropathy can also occur, as well as body and joint pain, headaches and more.  Heart rhythm disruptions including tachycardia are classic symptoms of thiamine deficiency.  Heart attack patients are routinely administered thiamine now.   Blood tests for vitamins are notoriously inaccurate.  You can have "normal" blood levels, while tissues and organs are depleted.  Such is the case with Gastrointestinal Beriberi, a thiamine deficiency in the digestive tract.  Eating a diet high in carbohydrates, like rice, starches, and sugar, can further deplete thiamine.  The more carbohydrates one eats, the more thiamine is required per calorie to turn carbs into energy.  Burning stored fats require less thiamine, so in times of thiamine shortage, the body burns fat and muscles instead.  Muscle wasting is a classic symptoms of thiamine deficiency.  A high carbohydrate diet may also promote SIBO and/or Candida infection which can also add to symptoms.  Thiamine is required to keep SIBO and Candida in check.   Thiamine works with Pyridoxine B 6, so if Thiamine is low and can't interact with Pyridoxine, the unused B 6 accumulates and shows up as high.   Look into the Autoimmune Protocol diet.  Dr. Sarah Ballantyne is a Celiac herself.  Her book "The Paleo Approach" has been most helpful to me.  Following the AIP diet made a huge improvement in my symptoms.  Between the AIP diet and correcting nutritional deficiencies, I felt much better after a long struggle with not feeling well.   Do talk to your doctor about Gastrointestinal Beriberi.  Share the article linked below. Thiamine, gastrointestinal beriberi and acetylcholine signaling https://pmc.ncbi.nlm.nih.gov/articles/PMC12014454/ Keep us posted on your progress!
